ROD-COUPLING'.

Specication of Letters Patent.

Patented May 18, 1909.

Application filed July 10, 1907. Serial N o. 383,159.

To all whom 'it may concern:

Be it knownthat l, BENGAMIN F. COLE, a citizen of the United States of America, residing at Menardville, in the county of Menard and State of Texas, have invented new and useful Improvements in Rod-Couplings, of which the following is a specification.

This invention relates to shaft couplings designed more particularly for use in connectmg the sucker rod of a windmill pump, and one of the principal objects of the invention is to provide means for coupling the two sections of the sucker rod and to permit the same to be readily uncoupled and to be quickly coupled whenever required.

Another object of the invention is to provide a male and female coupling member `formed upon the meeting ends of the sections to be coupled, and a sliding sleeve to cover the coupling members and to prevent them from displacement., said sleeve being adapted to be quickly slid upon one of the members to permit the sections to be readily uncoupled and to provide means whereby they may be quickly recoupled Whenever required.

These and other objects may be attained by means of theconstruction illustrated in the accompanying drawing, in which:

Figure l is an edge view of the coupling. Fig. 2 is a side view in which the sliding sleeve is shown in section. Fig. 3 is a detail perspective view of the sliding sleeve. Fig. l is a detail perspective view of the male and female members of the coupling.

Referring to the drawing for a more particular 'description of my invention, the numeral 1 designates the lower end of the pitman of a windmill, and 2 is a stirrup formed upon the upper end of the shank 3, said stirrup being connect-ed by bolts 4 to the pitman 1. The shank 3 is rectangular in cross section, and formed in the lower end of said shank is a rectangular aperture 5 provided with a reduced slot 6 at the lower end thereof which communicates with a rectangular aperture 7, and extending from the aperture T is a narrow slot 8 which extends entirely through the end of the shank 3. For convenience this section may be called the female member.' t,

The maleJ member consists of a bifurcated portion 9 between which is bolted the lower section l0 of the sucker rod or pitman, these parts being connected by suitable bolts 11 Formed upon t-he upper end of the bifu.

cated portion 9 is a rectangular shoulder 12 and formed integral with this portions an oppositely projecting ange 13 extending from which is a narrow neck 14. Above the neck 14 is a pair of oppositely disposed lugs l5 and above the lugs 15 is a narrow shank 16 upon which an enlarged head l' is formed. This portion of my device ma be termed the male member, and is adapte to fit within the recesses 5 and 7 and th' connected slots 6 and 8, said two membe' A then lying Hush upon their outer surfacf A sliding. sleeve 18 fits over the male a -female members to hold them in connectand a locking pin 19 extends through i A opening 2O in the sleeve and through a he: 21. in the shank 3. The operation of my invention may b,

briefly referred to as follows: Whenever it is required to uncouple the pin 19 is withf drawn, the sleeve 18 is slipped upward, and the male member is withdrawn from the female member in an obvious manner'. henever it is required to recouple, after the male member has been placed in position. the sleeve 18 is slipped down and the pin 155 passed through the parts to hold the san,r in coupled relation. From the foregoing it will be obvious tha my coupling is of slmple construction, cal.

be operated quickly to connect or disconne\^+ the two members, and that a single key c bolt is used for holding the parts in operi tive position.

Having thus described the invention, what l claim is: A shaft coupling comprising a shank with a series of rectangular recesses extending centrally through the same and having a plurality of narrow slots communicating therewith and also extending centrally through the shank, said shank having a passa-ge formed therethrough adjacent to one of said recesses, a bifurcated member having a shoulder on its upper end and a lia ge contiguous therewith, a plurality of nari w necks extending above said flange, a pl.

rality of rectangular heads disposed intel mediate of sa-id necks, said necks and said erst AVAILABLE COPY is respectively being adapted to fit in recess and slots respectively formed in tid shank, a sleeve carried by the shank dapted to be slidabiy mounted over the )int of said member and said shank and aving the lower portion of its surrounding 'a'll and its bottom edge contacting reectively with said flange and said shoul- .nii

der and a pin inserted through the sleeve and shank, substantially as specified. 10 In testimony whereof, I aix my signature in presence of two witnesses.
